FOLDING BED-SEAT.

To all wh-0m it may concern.'

Be it known that'we,AXELEoKBERG, a

citizen of the United States, and GUsTAF OHRs'rRoM,

and more particularly to improvements in l folding bed-seats.

A*agonal The primary obj ect of our invention is the provision of afoldinglbed-seat which is durable inl construction, simple to operate,and which contains few parts so that the possibility of wear on themoving parts when folding or extending r,the seat `is reducedto theminimum. ,i p

Another object of our invention is the production of a yielding -f 'seator supporting member which will not sag from use, and in whichfthestretches ployed in articles of furniture ofy this'type are atall timesretained in flattenedv condition. l

' Another object of ourinvention is to provide spring supporting devicesfor the seat member having integral connector parts whereby the'separate connections usually employed are dispensed withl and consequentwear avoided. v

.Anotherobj ect of our invention isthepro vision of diagonal webbingsinterwoven with cross or transverse webbings in such a manner thatthelatter are at all times retained in flat condition, and toso supportvand lace or thread the diagonal ywebbings through supportingelementsthat theyar'e themselves at,

all times retained in flatl condition, the diand cross ywelobingsproviding a flat support for the bedding and body.

Other objects of our invention are, to connect the-folding or'collapsible side supporting members of the seat insucha manner that theycannot spreadV under -weightsup- Vported thereby, and to otherwiseimprove on folding articles' of furniture v.now in use.

' To these ends the invention consists in the lnovell features ofconstruction, and in the arrangementL )and combination of parts -to -be'hereinafter "described and particularly pointed outin thesubjoinedclaims.

In the drawings,f-Figurelis a side eleva- 'tioiiy of affolding bed-seatembodying my invention. ffFigrQ is a plan view of the'same.

Fig. 3 Jisan enlarged cross section taken on line 3 3, Fig. l. Fig. 4 isa side elevation ofthe .bed-.seat as it appears when folded. Figv is adetached perspective view of one of the spring supporting devices forthe webbmg. F ig. 6 is a perspective view of a modified form of springsupporting device.

Referring now to the drawings in detail,

v like numerals of reference referto like parts in the several figures.

The reference numeral l7 designates the y folding or collapsible sidemembers of the bed-seat, each of which is preferably constructed of twosets of parallel wooden or metallic bars 8 arranged diagonally, the barsof each oflsai'd sets being adapted lto cross those of the other, as at9, and have their upper ends meet the upper-ends of said other set,'.towhich they are pivotallysecured, as at l0. At their points of crossingthe 'bars of both sets are also pivotally connected together. `While.the exact arrangement and connection of these side bars providecollapsible members which are capable of supporting heavyv weightswithout unduly straining the connections, it is nevertheless ourintention that such arrangement and connection may be changed withoutdeparting from our invention, as' it is possible to constructcollapsible side members otherwise than herein shown and ldescribedwhich of articles-constructed to fold accordeon-like are now in use. vWenevertheless consider the eXact arrangement and connection yof ofconsiderable importance, due to the sustaining qualities of the same. Atintervals lalong the length of these folding side members, dove-tailedtransverse grooves 12 are formed in several of the bars near their upperand lower ends,'in which grooves are entered'the flaring ends 13 oftransverse conv nector rods 14, said rods serving to tie the would becapable of use in connection with other parts of our bed-seat, asvarious forms -bars constituting the folding side members structionsbecome loose and permit the foldv ing side members to spread when theseat supports a load. A Y f 15 designates a supporting member whichcomprises'yielding supporting devices 16 secured to the upper ends ofthe side members springwform, as at 19, and'eXtended in oppol,sitedirections from said `spring to provide 7 and webbings 17, 18, spanningthe vspace betweensaid supporting devices'at opposite sides of the seat.16 are arranged in two series, one series be'- ing securedto the top ofeach collapsible vside member and thesupporting-devices of' one seriesbeing directly opposite thoseof the other. In preferred form, eachsupportingdevicev is Constructed of a single piece of wire coiledapproximately.' midlen'gth Vinto spiral# at one enda combined pivotand'securing member 20 and at itsother end a connector 21. Thesecuring-member Q0 is formed by rebending the wire Vinto UV-foriiiation,the eX- tremity ofthe wire at this end being thrust through registeringopenings inv the upper 'ends of two meeting bars 8 andserving as a pivotconnection for said bars, the extremity being suitably headedif desired,as at 22, so'as to prevent'withdrawal from said bars. yThe connector 21is preferably formed b f bendinoflthe wireinto triangular loo form,through which' the .webbings 17., 18 are laced or threaded. Theopposite. sup- --Yporting-devices ,areV connected together. by

` stretches of crosswebbings17, thev webbing being passed. around thetransverse or base portion 28 Vof .the triangular loops 2-1and riveted,sewed,or l.otherwise lsecured thereto.

.Two V'stretchesv of diagonally-arranged webr-bings 18 are provided, theends'of thesanie being riveted or otherwise secured to the two endstretches of cross webbings,'as at 24:,

t ieachstretch of diagonally-disposed webbing v being laced orthreaded.throughialternate loops at oppositesidesv of the seatand passedl.above and beneathadjoining cross'webbings atv opposite :sides of theseat. f Theitwon stretches of diagonalw'ebbings cross each other atpoints between the cross webbings,

each stretch passing'alternately above and be- Y A'ne'ath the other;thus keeping said diagonal webbings stretched-theirfull width'andpreventingthem turning edgewise when the seat Y is extended for use yasabed. .The spring v Vsupporting-devices 16 and the webbings 17,

18, Vconstitutean elastic, even surface for the occupants body. v

In the modilicationshown in Fig. .6, the

and smooth v vsupporting-device is formed in threepieces,

ltended `one being a coil-spring 25 havingone end of lthe'wire forming'the same bent into hook form, as at 26,Y and the other end vbeing eX-Va trifle from the spring,as at 27, `and its end bent into hook form, asat 28 The i hook QGis adapted to engage a triangular loop 29, throughwhich Vthe webbings 17 18, are'` to be laced and thehook 28 ispassed'througli Van opening formed ink a metallic securing ",memberySObent'at aright angle, as'at 81,

i .and adapted tobesecured to the upper ends lof the `bars 8.

The constructions described provide The supporting-devices the Yyieldingmeinberof the Vsupporting vdevice, andthe base or transverse bar servesto,

hold .the webbings-secuiely thereto iniiatspringlsupported triangular.loop, the apex i of which has Vcoiitiiii'iedior secured thereto tenedcondition Vat all times, thus''avoiding turning of these fwebbingsedgewise. A Vvery important feature of lthese webbings lies in themanner'in which Vthe diagonally-.disposed webbings arearranged withreferenceto theftransverse jwebbings,y attention being invited to the'fact thatthevends Vof the transverse and beneathfon'e of the ends zofalternate transverse vwebbin'gs and beneath'- and above i A webbingshave lying against tlieirjppposite faces the oppositely-directedportions of the Y' diagonally-disposed :webbin gs, eachofjsaiddiagonally-disposed webbings passing 'above' the opposite ends oftheintermediate-trainsverse webbings, and when the'diagonal.web;Vv bingsare properly stretched they will .retain f the transverse webbings inA'flattened s condition byrea'sonof theirA passing through the Y of thetriangularly widened' inner YendsV formed loops.V
